Hebrews 10:25(NIV)

Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching

Ecclesiastes 4:9-12(NIV)

9 Two are better than one, because they have a good return for their work:
10 If one falls down, his friend can help him up. But pity the man who falls
and has no one to help him up!
11 Also, if two lie down together, they will keep warm. But how can one
keep warm alone?
12 Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken.
